See additional need-to-know information on OTC injections for citrus from a UF/IFAS Extension publication.
In our last blog, we shared suggestions for the timing of OTC injections from a UF/IFAS Extension publication, “Suggested Use Pattern of Injectable Antimicrobials for Huanglongbing (HLB) Management (April 2024).” The publication shared additional information on OTC injections. See the details below.
Additional Information on OTC Injections
The publication advised that “This is not an official University of Florida recommendation. Information is based on FIFRA Section 24(c) Special Local Need Label for ReMedium TI ®(10/28/2022) and Rectify (01/30/2023).” It shared the following need-to-know information on OTC injections:
Information on Injection Sites
- “Do not re-use injection sites.”
- “The rootstock is the recommended location for injection, but scion injections are also effective.”
- “Subsequent injections should be above or below the initial site by 2 inches and on the opposite side, or to the right or left by 2 to 3 inches.”
- “Do NOT use any post-wounding treatments as these may interfere with wound healing.”
- “Injection into the trunk can cause significant damage to the tree.”
- “Trees with a trunk diameter of less than 2.5 inches are prone to more damage.”
- “Minimizing the hole size will minimize tree damage.”
- “Muriatic acid is highly corrosive and can cause severe skin burns and eye damage. Do not inhale fumes.”
- “Injection of oxytetracycline dissolved in an acidified solution may cause trunk damage with long-term effects that are not yet established.”
